How To Diagnose And Fix A High Idle On Dirtbike!

Тәжірибелік нұсқаулар және стиль

A very high idle can be caused by an air leak or the throttle assembly. Air leaks are common along the air boot or the intake manifold. If you are more unlucky an air leak can appear in your left crank seal. Check the easy things first starting with your air filter, then moving along towards your throttle assembly to make sure your cable is not sticking. My problem ended up being a chipped carb slide.

    I'm having a problem with my suzuki Ax100 2 stroke , once i turn the fuel off, and the fuel in carb bowl is about to get get over, the bike shoots up in RPM, i know it gets a bit lean, my Yamaha does the same thing, but the bike dies in a few seconds, but my suzuki doesn't, it just shoots up and up...even Turning the ignition off won't kill the engine, it still keeps running ( rpm about 10k+) what could possibly be wrong? Another thing i noticed is that the carb becomes so chill, like an ice cube when the bike is running. Any help appreciated

    My guess is air leak or stuck throttle cable. You can't kill the bike because the kill switch is being overpowered by the spark from your engine turning. Also the carb becomes cold to the touch the same way refrigerators do. I'd check the cable first and if that doesn't work put some heavy grease over any engine gaskets or possible carb leaks and see if your revs go down.

And also when I pull the choke up it idles fine b when I put it down it high idles. I literally have no clue what it could be. It could honestly be more than one thing b I doubt it would be the crank seals cause I just chnaged them a few months ago

    I need help. I fell off of my bike doing a wheelie like a moron. I had to replace the silencer, because the hanger was bent. The header pipe has a slight bend, but the new fmf slid right on and I put the bolts in. It starts fine. If I rev it, it will continue to stay loud. Air screw position is within spec. Idle screw doesn’t really do anything. It just holds the rev even when I’m not revving it. The bike also goes by itself without any throttle. When I have the kickstand down it will move on it’s own. Also when I fell off my throttle was stuck. I took the throttle apart and I fixed that issue. Throttle feels normal. Please help if you can. Thanks.

After putting everything back together, I started having extremely high idling. Almost as though the throttle is wide open. I checked the throttle cable, and there seems to be no issues. It doesn’t stick, and completely closes as normal. And I never had any issues with this bike before. I also never touched the carb. My bike was idling perfect before the rebuild. What could it be?

    Regardless, self-ignition is not good. Maybe you accidentally filled er up with diesel and it was able to ignite? Sounds goofy but check that first. If not it's probably not a bad idea to do a compression test and change spark plugs or check your top-end clearances entirely. I don't think this has much to do with your carb. @@Body_Dropped
